WINDOW-SHADE ADJUSTER.

SPECIFICATION forming part of Letters Patent No. 755,835, dated March29, 1904.

Application filed November 28, 1993. Serial Nol83,062. (N0 model.)

To all whom it may concern.-

Be it known that I, RUE AToN, a citizen of the United States, residingat Independence, in the county of Montgomery and State of Kansas, haveinvented new and useful 1m provements in Window-Shade Adjusters, ofwhich the following is a specification.

This invention relates to window-shade adjusters; and the primary objectof the same is to provide a simple and comparatively inexpensive deviceof this class adapted to be readily applied to a window-frame and easilyoperative to bodily raise and lower a windowshade and the rollercarrying the latter to permit free entrance of air through the upperportion of the window and alsoto enable the lower or intermediate partof the window to be covered by the shade without shutting out the lightentirely.

The invention consists in the construction and arrangement of theseveral parts, which will be more fully hereinafter described andclaimed.

In the drawings, Figure 1 is an inside elevation of'a portion of awindow frame and shade, showing the improved adjuster applied thereto.Fig. 2 is an. edge elevation of the window-frame broken through toillustrate the construction of the improved adjuster.

Similar numerals of reference are employed to indicate correspondingparts in the views. The numeral 1 designates a window-frame of usualform having upper and lower sashes 2 and 3. At opposite sides of theframe 1 vertically-disposed guide-rods 4 are secured, one at each sideof the frame, each of the rods having an upper angular extremity 5, witha pointed terminal 6 to adapt it to be driven into the upper part of thewindow-frame, and a lower shouldered arm 7, with a pointed support 8,having an ornamental ball or other arrangement 9 at the angle ofintersection with the rod. Adjustably mounted on the rod is ashade-slide 10, consisting of a straight wire member 11, havingguide-coils 12 at its upper extremity continuing into an outstandingbracket or support 13, with a seat 1 1, the seat in one bracket beingadapted to receive the flattened trunnion 15, controlling the winding ofthe spring of a shade-rollerlG, on which is secured and operates anordinary shade 17.

The seat of the opposite bracket will be of diflerentform to accommodatethe cylindrical trunnion at the opposite end of the shaderoller. This isan obvious advantage in the construction and has not been shown, as itwill be readily understood in the art. At the upper terminal of thebracket a guide-eye 18 is formed and engages the rod 4, as do' also thecoils 12, the said guide-eye and coils serving to movably connect theupper extremity of the shade-slide to the rod 4 in such manneras toprovide a stable support for the shade-roller and shade. The lowerextremit of the wire 11 is bent into a rearwardly-extending coil or loop19 for the purpose of establishing a spring action, and from the said,coil or loop 19 an arm 20 continues outwardly and is bent into aguide-coil 21, surrounding the rod 4 and normally disposed at a downwardangle of inclination. A finger-loop 22 continues from the coil 21 and isalways adjacent to an auxiliary loop 23 above, which is disposed at anupward angle of inclination and continues from a locking-coil 2 1, alsosurrounding the rod 4 and having an extension 25 projected rearwardly toone side of the spring-coil 19. The extension 25 forms part of abearing-arm 26,'.having a lower extremity loosely movable in the coil 19and the upper end bent at an inward angle to provide a bearing-head 27,which normally engages the rear portion of the wire 11 to give thelocking-coil and finger-loop a resilient resistance suflicient to causesaid parts to normally stand at an upward angle of inclination, asshown, so that a forceful bite or clamping action on the rod 4 by thelockingcoil 24 will ensue.

The construction and arrangement of parts at the opposite side of thewindow-frame is similar to that just specified, as it will be understoodthat both sides of the shade will have to be equally adjusted to preventthe same from standing at an irregular angle when moved. In operatingthe slide to adjust the shade the loops 2-2 and 23 are grasped and loop23 pressed toward loop 22 against the spring resistance of the coil 19and the bearing-arm 26. By drawing the loop 23 toward loop 22 the coil 2L will be drawn toward a horizontal plane and relieved from a clampingengagement with the rod 4:, and while the said coil is so held bycontinual pressure exerted on the loops 22 and 23 the slide may be movedeither up or down on the rod any distance desired. After the adjustmentof the shade has been attained the finger-loops 22 and 23 are released,and immediately the coil Qt bites or clamps on the rod through themedium of the spring-coil19, having a resistance set up therein by thearm 26, terminally engaging the head 27 on the wire 11, and therebyresist accidental downward movement of the shade.

It will be seen that the construction and arrangement of the severalparts are exceptionally-simple and the cost of manufacture andapplication are reduced to a minimum. It is proposed to ornament the rodand slide by plating, andchanges in the proportions, dimensions, andminor details may also be resorted to without departing from the spiritof the invention.

It is intended in some instances to support the shade-roller inconnection with any of the well-known forms of adjustable frames or toemploy a roller which of itself is adjustable to vary its length, sothat one roller or frame may be used to accommodate windows of differentwidths.

Having thus fully described the invention, what is claimed as new is 1.In a window-shade adjuster, the combination with a shade-roller andshade, of guiderods, and slides movably engaging the said guide-rods andhaving upper brackets to support the shade-roller, a lowerupwardly-inclined clamping device, and a lower guide, the lower clampingdevice and guide each having outWardly-projecting finger-engaging meansat reverse angles to each other.

2. In a window-shade adjuster, the combination with a shade-roller andshade, of guide devices, shade-slides having opposite extremitiesembracing the guide devices, the said slides having supporting means attheir upper extremities to engage the shade-roller, andupwardly-inclined clamps partially embracing the guide devices andhaving inner upwardlyextending resilient arms bearing on the guidedevices.

3. In a Window-shade adjuster, the combination with a shade-roller andshade,of a guid erod, slides movably mounted on the guide-rod and havingupper terminal brackets forming a part thereof to support theshade-roller, lower resilient coiled clamping members standing at adownward inclination around the said devices, and lower guide-coilssurrounding the guide devices and disposed at upward angles ofinclination and continuing into rear bear-. ing-arms which engage aportion of the slides.

4. In a window-shade adjuster, the combination with a shade and itsroller, of guiderods, shade-slides having guide-coils at oppositeextremities embracing the guide-rods, and brackets projecting above theupper coils, the lower portions of the slides having inwardlyextendingeyes, and clamping devices having. portions embracing the guide-rods,and members projecting through the eyes and terminating inupwardly-extending arms which bear on the rods.

5. A window-shade-adjusting means, adapted to be applied to oppositesides of a Windowframe and consisting of a vertically-disposedguide-rod, a slide having coils at oppositeextremities embracing thesaid rod and a bracket terminating in an eye also embracing the rod, thelower part of the slide having an inwardlyprojecting eye, and a clamphaving acoil embracing the guide-rod and a member projecting through theeye at the lower part of the slide, the said member continuing into anupwardly-extending arm which bears against the slide.

In testimony whereof I aflix my signature in presence of two Witnesses.

RUE ATON.
